Android: dynamically setting links to text in strings.xml
- by Martyn
I'm trying to make an app with localisation built in, but I want a way that I can create a web link within the text, the URL being defined elsewhere (for ease of maintenance).
So, I have my links in res/values/strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
...
<string name="link1">http://some.link.com</string>
<string name="link2">http://some.link2.com</string>
</resources>
and my localised text in res/values-en-rGB/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
...
<string name="sampleText">Sample text\nMore text and link1\nMore text and link2.</string>
</resources>
I've not tested this bit, but from the localization section of developer.android.com it says that this approach to reducing content duplication should work, although I'm not sure what folder I should put Italian, for example. Would it be in 'res/values-it-rIT/strings.xml'? Lets assume that I have various other languages too.
I'm looking for a way of taking the base localised 'sampleText' and inserting my html links in, and getting them to work when clicked on. I've tried two approaches so far:
1,
Putting some formatting in the 'sampleText' (%s):
<string name="sampleText">Sample text\nMore text and <a href="%s">link1</a>\nMore text and <a href="%s">link2</a>.</string>
and then processing the text like this:
TextView tv = (TextView) findViewById(R.id.textHolder);
tv.setText(getResources().getString(R.string.sampleText, getResources().getString(R.string.link1), getResources().getString(R.string.link2)));
But this didn't work when I click on the link, even though the link text is being put in to the correct places.
2, I tried to use Linkify but the regular expression route may be difficult as I'm looking at supporting non-Latin based languages. I tried to put a custom xml tag around the link text and then do something like this:
Pattern wordMatcher = Pattern.compile("<span1>.*</span1>");
String viewURL = "content://" + getResources().getString(R.string.someLink);
Linkify.addLinks(tv, wordMatcher , viewURL );
But this didn't work either.
So, I'd like to know if there's a way of dynamically adding multiple URLs to different sections of the same text which will link to web content?
Thank you,
Martyn
